THE COUNTRY HOME [CHAPTER 
Grape.—Treat with iron sulphate before the 
buds start in the spring. Use Bordeaux to prevent 
black rot just before blooming; repeat just after 
the fruit is set, and again a few weeks later. For 
beetles and bugs apply Paris green as soon as they 
appear. 
Pear.—Treat as you do the apple. For blight 
cut off the limbs some inches below the affected 
part, and burn. For psylla and slug apply kero- 
sene emulsion, quite strong, and repeatedly, or 
whale-oil soap, one pound to ten gallons of water. 
If the scab appears on the pear or apple apply Bor- 
deaux repeatedly. 
Plum.— Use Bordeaux before the buds open, and 
again after the fruit is set, repeating occasionally. 
If leaf blight occurs, Bordeaux again. Cut away 
black knot, and apply Bordeaux. 
Cherry.— Cut away black knot and burn it. 
Apply arsenites for slugs, and treat aphis with hel- 
lebore; try also kerosene emulsion. Repeat the ap- 
plication every ten days, or oftener. 
Potato.—For blight use Bordeaux when the 
vines are six inches high; repeat every two or three 
weeks. To prevent potato scab do not plant any 
scabby seed, and soak uncut seed potatoes one hour
